[0002] A painting robot, also known as a spraying robot, is an industrial robot that can automatically spray paint or other coatings. A painting robot is mainly composed of a robot body, a computer, and a corresponding control system. A hydraulically driven painting robot also includes a hydraulic oil source, such as an oil pump, an oil tank, and a motor. Most of them use a 5- or 6-degree-of-freedom articulated structure. The arm has a large movement space and can perform complex trajectory movements. Its wrist generally has 2 to 3 degrees of freedom and can move flexibly. The wrist of the more advanced painting robot uses a flexible wrist that can bend and rotate in all directions. Its movements are similar to those of a human wrist, and it can easily reach into the workpiece through a smaller hole to spray its inner surface. Painting robots are generally hydraulically driven and have the characteristics of fast movement speed and good explosion-proof performance. Teaching can be achieved through hand-to-hand teaching or point indication. Painting robots are widely used in process production departments such as automobiles, instruments, electrical appliances, and enamel.

[0019] A fixing plate 23 is fixedly provided on the upper surface of the base 1, and the fixing plate 23 is in an inverted L shape. A first motor 24 is fixedly provided on the fixing plate 23, and the output shaft end of the first motor 24 is fixedly provided on the half-face gear 22; the half-face gear 22 can be driven by the first motor 24.

[0020] A first positioning block 3 is fixedly provided on the upper surface of the base 1, a fixed block 31 is movably provided on the upper surface of the first positioning block 3, a second positioning rod 32 is rotatably provided in the fixed block 31, and a positioning wheel 33 is fixedly provided on the second positioning rod 32; the positioning wheel 33 contacts the rubber block 16, so that the rubber block 16 can be driven to rotate, because a connecting rod 14 is fixedly provided on the rubber block 16, and one end of the connecting rod 14 away from the rubber block 16 is fixedly provided on the lower surface of the storage table 15, when the rubber block 16 rotates, the storage table 15 with the belt rotates together.

[0021] The fixed block 31 is fixedly provided with symmetrically distributed sliders 34, the first positioning block 3 is fixedly provided with symmetrically distributed second positioning blocks 35, the second positioning block 35 is provided with a slide groove 36 at one end close to the fixed block 31, and the slider 34 is slidably set in the slide groove 36; through the mutual cooperation between the slider 34 and the slide groove 36, the moving path of the fixed block 31 can be limited.

[0022] A cylinder 4 is fixedly disposed on the upper surface of the first positioning block 3 , and the output shaft end of the cylinder 4 is fixedly disposed on the fixing block 31 ; the fixing block 31 can be pushed by the cylinder 4 to move.

[0023] A third positioning rod 42 is rotatably disposed in the fixing block 31 , and a belt 43 is directly and jointly rotatably disposed between the second positioning rod 32 and the third positioning rod 42 ; the belt 43 allows the second positioning rod 32 and the third positioning rod 42 to rotate synchronously.

[0025] Working principle: When in use, the staff fixes the painting robot on the rotating table 13, and then the staff places the workpiece to be painted on the storage table 15, and then starts the device. Because the output shaft end of the first motor 24 is fixedly set on the half-face gear 22, when the first motor 24 is working, it will drive the half-face gear 22 to rotate. Because the half-face gear 22 is meshed with the gear 2, and the gear 2 is fixedly set on the rotating rod 11, when the half-face gear 22 rotates, it will drive the rotating rod 11 to rotate. Since the rotating plate 12 is fixedly set at the end of the rotating rod 11 away from the base 1, a plurality of equally spaced connecting rods 14 are penetrated on the rotating plate 12, and a storage table 15 is fixed on the connecting rod 14, so that when the rotating rod 11 rotates, the position of the storage table 15 will be moved, so that one of the storage objects can be placed on the rotating rod 11. The platform 15 moves to the front of the painting robot to paint the workpiece on the storage platform 15. At the same time, the cylinder 4 pushes the fixed block 31 to move in the direction of the connecting rod 14, so that the positioning wheel 33 contacts the rubber block 16. At the same time, the second motor 41 drives the third positioning rod 42 to rotate. Because the third positioning rod 42 and the second positioning rod 32 are rotated together with a belt 43, when the third positioning rod 42 rotates, the second positioning rod 32 will rotate with it. Since the positioning wheel 33 is fixed on the second positioning rod 32, and the rubber block 16 is fixed on the connecting rod 14, when the rubber block 16 contacts with the positioning wheel 33, it will rotate with it, and at the same time drive the storage platform 15 to rotate, so that the workpiece on the storage platform 15 rotates, and the workpiece is evenly painted by the painting robot.
